导热凝胶和硅凝胶是同一种吗?它们有什么区别?
Thermally conductive gels and silicone gels are not the same material, and they differ significantly in several ways. Basic definition and composition
Thermally conductive gel: It is a gelatinous silicone-based thermally conductive material, which is made of silicone resin, cross linker, and thermal conductive filler through stirring, mixing, and encapsulation and solidification. It combines the advantages of thermal grease and thermal pads while avoiding the disadvantages of both. Thermally conductive gels have extremely high thermal conductivity, can fill gaps, and have high adhesion.
Silicone gel: Although it also contains the word "gel", its specific composition and application may be different from that of thermal conductivity and gel. Silicone gel usually refers to a gel material with silica gel as the main component, and its properties and applications may be more extensive, not limited to the field of thermal conductivity.
Performance characteristics:
Thermally conductive gel:
1、The texture is soft, with almost no hardness, and has a strong surface affinity.
It has the characteristics of good shape recovery, strong material cohesion, high heat resistance, and good long-term thermal stability
The thermal resistance is extremely low, which can fill the gaps and effectively transfer heat, white
2、 It can be divided into two types: one-component and two-component, of which two-component thermally conductive gel needs to be mixed and cured with part A and part B before silicone gel can be used (specific properties vary depending on the type):
3、 It may have excellent elasticity, sealing, temperature resistance, aging resistance and other characteristics.
4、In different applications, its performance characteristics may be focused. Fields of application
Thermally conductive gel: It is mainly used in electronic devices with high heat dissipation requirements, such as heat dissipation of core components such as CPU, GPU, and LED lights. It can effectively fill the tiny gaps between these parts and the heat sink, improving heat dissipation efficiency.
Silicone gel: Due to its wide range of performance characteristics, silicone gel has applications in many fields such as medical, electronics, chemical, and automotive. For example, in the medical field, silicone gel can be used to make artificial organs, drug carriers, etc.; In the field of electronics, silicone gel can be used to make sealants, potting adhesives, etc. IV. Conclusions.
In summary, there are obvious differences between thermally conductive gels and silicone gels in terms of basic definition, composition, performance characteristics and application fields. Thermally conductive gels are more focused on thermal conductivity and applications in the field of heat dissipation, while clams gels have a wider range of applications and diverse performance characteristics. Therefore, when choosing materials, it is necessary to choose according to the specific application scenarios and needs.
